Abstract
Disclosed is a method for producing liquid containers by: producing a plastic container by a blow moulding process; filling the plastic container with a flowable medium, such as a liquid; and at least partially closing the container, which is filled with the liquid, with a container closure. After the at least partial closing of the container, a gaseous medium is fed to the interior of the container via at least one opening introduced into at least one portion of a wall of the plastic container or a circumferential wall of the container closure or via an intermediate space which exists between a mouth and the container closure.
Claims11
A method for producing liquid containers and in particular beverage containers, comprising the steps of:
- producing a plastic container by a blow moulding process;
- filling the plastic container with a flowable medium;
- at least partially closing the container, which is filled with the liquid, with a container closure;
- wherein, after the at least partial closing of the container, a gaseous medium is fed to the interior of the container via at least one opening introduced into at least one portion of a wall of the plastic container or a circumferential wall of the container closure, wherein the opening via which the gaseous medium is fed to the container is closed after the feeding of the gaseous medium, and wherein the closing of the at least one opening is carried out by a relative rotation of the container closure relative to the container.
An apparatus for producing containers filled with a liquid comprising
- a transforming device, which transforms plastic parisons into plastic containers,
- a filling device which is arranged downstream of the transforming device in a transport direction of the plastic containers and which fills the plastic containers with the liquid, and
- a closing device which closes the liquid-filled plastic containers at least partially with container closures, wherein the apparatus has a gas feed device which feeds a gaseous medium to the containers during or after the closing process, wherein the gas feed device is configured for feeding the gaseous medium to the containers through an opening which is formed in a container wall or a circumferential wall of the container closure, wherein a further closing device is configured for closing the opening by a relative rotation of the container closure relative to the container.
